This is a slider-puzzle game. There are ten stages at each level: easy (3 * 3), normal (4 * 4), and hard (5 * 5). As for the pictures, they are of anime-style girls. No real skin is shown... at least without the DLC. Thing is, the picture is the same for all three levels. The DLC levels are topless on easy, bottomless on normal, and without (most) clothing on hard.

3 steps for pictures. it has hentai option as well which is same picture with top and bottom. the artwork is pretty good and the music is relaxing. it does get harder but of course you can hit h to complete the level.
